Specification-of Letters Patent.

' Application filed October 3, 1906. Serial No. 387,293.

ToalZ whom; it may concern: Belt known that I, EMIL BAUMANN, a citizen of the United States, residing at St.

Louis, in the State of Missouri,- have invented presented at various angles to the wind for new and useful Improvements .in Air-Ships,

'of-which the following is a specification.

propelling and steering the ship. 4

Another object of my invention. is to rvide an airship, made buoyant by a gas :1 with oppositely disposed aeroplanes eadh carrying a series of balanced vanes and both "of said aeroplanes being-rotatable in the same direction-and adjustable at various angles to control the direction of the ship.

These and other objects may be attained by means of the construction. illustrated in 2- is a front elevation of the same.

the accompanyi drawing, in which:

Figurel is a side elevation of an airship made inaccordance with my invention. Fig. Fig. 3 is a side elevation similar to that" shown'in Fig. 1' with the aeroplane ina different position. Fig: 4 is a detail, perspective view-0f one of the vanes partially broken away.

vention, the numeral l design'ates an ordinary balloon or gas bag' connected by means of cords or ropes 2 to cross bars 3 secured to the frame 4 of the airship. I The frame 4 comprises oppositely disposed side pieces-which may be cut away to reduce their weight and a boat-like basket or hull 5 suspendedfrom the lower edges of said frame members." Mounted to rotate in the frame 4 are oppo-. sitely disposed cranked shafts 6, said shafts each having a horizontally exteuding mem-.

horizontal position.

zber 7 upon each of which is pivoted'an aeroplane 8. Pivotall vmounted in the aeroplane 8 is a series 0 vanes 9, each comprising a light frame 10 into which is properly' stretched a silk or other diaphragm 11, said vanes having outwardly projecting pintles '12. disposed above the horizontal centerjof said vanes in order that they may always assume a vertical position when theaeroplanes are -moving in an upward directionr When the aeroplanes move downward the impact of the air 1s sttflicient to move said vanes into a v Secured to the upper edge of the frame 10 is a hall or weight 13 from which a shank 14 extends to the frame 10, as shown more particularly in Fig. 4. A sprocket chain 15 is connected at its ends to theouter ends of the aeroplane S and said cl'iain passes around a sprocket wheel 16 mounted upon the end of a shaft 1-? which is provided with a hand wheel 18 for adjusting the aeroplane in various angularpositions fora purpose which will presently appear. I

To hold the aeroplanes in adjusted position, a pawl and ratchet 19 is The shaft 17 is mounted in a rot'ata le frame '20. the shaft 21 of which is journaled in the sprocket chain 24 which leads to a sprocket wheel 25 on the shaft of the motor 26. It is to be noted that there are two motors 26 which may be of the gasolene type or of other suitable character and. that the arrovlded.

rangement of aeroplane and vane is substantially identical upon opposite sides of the frame; hence a description of one will serve for both. The shaft 6 is provided with a horizontal member 6 which'extends through the frame 4 and is journaled in the bracket 6 secured to the inner wall of the frame 4.

A sprocket chain 27 extends around sprocket Referring to the accompanying drawings for a more particular description of my inwheels 28 secured to the member 6 of the shaft .6, said sprocket chain extending aroundsprocket wheels 29 on the shaft -21,"and the upper stretch of said sprocket chain extending in an inclined direction and passing around a. sprocket wheel on the shaft 30.

From the foregoing it will be understood that the: aeroplanes uponopposite sides of the machine are simultaneously rotated.

The 0 eration of my invention ma be briefly escribed as follows: The ba icon or. gas bag 1 -may be assumed to have sufiicient capacity to sustain the weight of the entire ship but need not be suflicient to ascend without the use of the aeroplanes and vanes. The motors 26 bein' started, theaeroplanes 8 are rotated upon their axes in the direction indicated by the arrows in Fig. 1 to carry the ship upward. The aeroplanes may be inclined mde endently by means of the hand wheels. 18, t 1e vanes assuming a vertical osition by'means of the construction descri ed. When it is desired to descend, the aeroplanes 8 are adjusted to the re uired angle of inclination to steer, ropgl, ascend, and descend, as will be im erstood. The vanes E) being properly balanced by means of the weight. 13 at the upper side oi the vane frame are more responsive to the action of the air than would be the case. ii the weights 13 were omitted and the air alone serving to actuate said vane.

From the foregoing, it will be obvious lhat an airship made in accordance with'my invention and provided with a buoyant bag or sack containing suflicient gas to poise the ship will permit the aeroplanes and vanes to control the ascension and directionthcreol' Without having to overcome the weight of the ship.

:Various changes in the details of construetion may be resorted to without departing from the spirit and scope ol my invention.

Having thus described my invention, what I claim is:

1. An airship comprising a buoyant medium of just sufiieient capacity to sustain the weight of the entire air ship, a frame connected to said buoyant medium, crank shafts mounted in said frame, aeroplanes pivotally mounted on said crank shal'ts, weighted vanes pivoted to the aeroplanes and hand wheels for adjusting the inclination of said aeroplanes.

2. An air ship comprising a buoyant bag, a frame to which said bag is connected, crank shal'ts journaled in said frame, aeroplanes pivotally connected to s'aid shafts, weighted vanes pivotally connected to said aeroplanes, drive chains connected at their ends to said aeroplanes, a shaft carrying a sprocket wheel engaging saidchain, a ratchet wheel upon said shalt, a'hand wheel on said shaft, a retatable frame to which said shaft is jonrnaled, aml-means for rotating said aeroplanes, substantially as described In testimony whereoll allix my signature in presence of two witnesses.
